# Machine Learning and Geospatial Modeling Reveal Telecommunication Tower Suitability, Deployment Priorities, and Digital Connectivity Gaps Across Ethiopia
This repository contains the code, predictor metadata, and reproduction instructions for the manuscript:
> **Reja, A. A. & Yasin, K. H. (2026).** *Machine Learning and Geospatial Modeling Reveal Telecommunication Tower Suitability, Deployment Priorities, and Digital Connectivity Gaps Across Ethiopia.* Manuscript under review.
The framework integrates open Earth observation, Demographic and Health Survey (DHS), and crowdsourced infrastructure data through a stacked ensemble of LightGBM, XGBoost, Random Forest, and MaxEnt classifiers under nested spatial block cross-validation. It produces a national 1 km suitability surface, an operational priority surface, and a digital-equity-adjusted priority surface that systematically reveals geographies of digital exclusion missed by conventional siting maps.

## Headline results
| Metric | Value |
|---|---|
| Tree-based AUC range (10-fold spatial CV) | **0.963–0.970** |
| LightGBM Brier score | **0.001529** |
| Greenfield-priority area | **109,630 km² (9.87% of national)** |
| Densification-priority area | **6,054 km² (0.54%)** |
| Spearman ρ (priority vs equity gap) | **−0.037** (essentially orthogonal) |
| Regional rank stability across 4 classifiers | **ρ = 0.91** |
| Variogram range of residuals | **7.45 km** (≪ 50 km block size) |
